Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lamp for a drying device which is useful for a drying device for paint used in an automobile repair shop.

[0002]

2. Description of the Related Art When a sheet metal is applied in an automobile repair shop or the like, a small-sized drying device that can be easily carried is used to dry the applied coating. As such a drying device, conventionally, a device using a far infrared heater, a device using a near infrared heater, or a device using an infrared lamp has been proposed.

The conventional far-infrared heater is illustrated as follows.
For example, as shown in FIG. 8, this heater has a rod shape as a whole, a heating element 1 such as a filament is inserted into a metal sheath (for example, a stainless steel tube) 2, and an insulating material is filled around the heating element 1. A far-infrared radiation (generating) substance is coated on the outer periphery of the metal sheath 2, and the far-infrared rays are radiated by the coating layer 3. Further, the conventional near-infrared heater is illustrated, for example, as shown in FIG. 9. In this heater as well, the whole is rod-shaped, and a heating element 1 such as a filament is inserted into a glass tube (for example, a quartz glass tube) 4. Further, while an inert gas, a halogen gas or the like is sealed in this tube, an airtightness preventing section 5 for preventing gas leakage is formed in the electrode sections at both ends of the glass tube 4. Further, when the conventional infrared lamp is illustrated, for example, as shown in FIG. 10, the lamp has an ordinary light bulb shape, and the heating element 1 such as a filament is inserted into a tube 6 of a sphere (for example, a glass sphere). The front surface of the tube 6 forms a focusing lens portion 6a, and the rear surface thereof forms a reflection lens portion 6b, while the lead portions 1a, 1a of the heating element 1 and the base portion of the tube 6 are provided with a screw-shaped standard cap 7 It is fixed to and can be attached and detached using a normal socket.

[0004]

However, there are advantages and disadvantages in each of the drying devices using the above heaters and lamps. For example, a drying device using a far-infrared heater has an advantage that there is almost no difference in color with respect to the heat yield with respect to the paint, but there is some influence by the temperature, the irradiation angle is relatively narrow, and the irradiation light is visually observed. It is impossible to do so, and moreover, as shown in the graph of FIG. 11, it takes a considerable time to radiate far infrared rays and the drying temperature (a temperature suitable for drying) is not reached quickly. There was a problem. In the case of this heater, the temperature rises slowly in the order of heating the heating element 1, increasing the temperature of the metal sheath 2, and radiating the far infrared radiation from the coating layer 3 by the far infrared radiating substance. It is considered that it takes time to raise the temperature of 2.

On the other hand, in the drying device using the near-infrared heater, although there are some differences depending on the color of the paint, there is little influence by the temperature and the irradiation angle is relatively wide.
The irradiation light can be visually observed, and moreover, as shown in the graph of FIG. 11, there are advantages that the irradiation time of the near infrared rays is short and the drying temperature is quickly reached. In this heater, the temperature rises quickly
It is considered that the heat is emitted from the glass tube 4 directly through the heating of the heating element 1 and the temperature rise of the filling gas inside. Therefore, at the time of use, there is a great advantage that the drying device can be used quickly and good working efficiency can be obtained, but on the other hand, since the filament of the heating element 1 is set to be long in the longitudinal direction of the glass tube 4, There was a problem in that it was vulnerable to shock. That is, there is a problem in durability, and it has been necessary to provide a means for protecting the heater mounting portion of the drying device from an impact, for example, a structure for applying a heat-resistant buffer agent to the mounting portion.

On the other hand, in the drying device using the infrared lamp, the temperature distribution tends to become non-uniform due to the attachment state of the filament and its shape, and the thermal efficiency for the paint is somewhat poor, but the far infrared heater or Compared to the near infrared heater, it is cheaper, and if a standard product (for example, E26 base) is used as the base 7, it can be easily and removably attached to most existing drying devices having sockets. Benefits are obtained. In other words, it is very easy to use.

Therefore, conventionally, in order to support a wide range of applications in an automobile repair shop or the like, a drying device using the far infrared heater, a drying device using a near infrared heater, and a drying using an infrared lamp are used. It is necessary to prepare several devices and the like, which causes problems such as increased equipment cost and required storage space for each device. Further, in the case of the far-infrared heater or the near-infrared heater, the drying area per heater (about 1 kW) is not so large, and about three heaters are required to dry a normal coating part. Moreover, since the unit price of one piece is high, there is also a problem that the drying apparatus itself becomes considerably expensive.

Therefore, the present invention focuses on a widely used infrared lamp drying device, and is a highly compatible lamp having a standard base, which emits far infrared rays and near infrared rays. The present invention provides a drying lamp, which allows a user to properly use one drying device as needed.

[0009]

According to a first aspect of the present invention, there is provided a drying lamp including a bulb having a frost layer on its surface, a base attached to the base of the bulb, and a front end of the base. And a hemispherical shade that covers the outer peripheral side of the bulb and a reflection mirror layer provided on the inner surface of the shade.

A drying lamp according to claim 2 of the present invention comprises:
A valve on the surface of which a coating layer for far infrared radiation is applied, a base attached to the base of the valve, a hemispherical shade attached to the front end of the base and covering the outer peripheral side of the valve, And a reflection mirror layer provided on the inner surface of the shade.

[0011]

Since the drying lamp of the above-mentioned claim 1 has the base, it can be easily attached to the infrared lamp drying device having a normal socket by only replacing the lamp. In addition, since the frost layer (a layer such as a satin layer having fine irregularities) is provided, an effective radiation state of light rays can be obtained.

Since the drying lamp of the second aspect also has the base, it can be easily attached to a drying device for an infrared lamp having a normal socket only by replacing the lamp. Further, since the coating layer for far infrared radiation is applied, an effective radiation state of light rays can be obtained.

[0020]

As is apparent from the above description, the drying lamp according to the present invention has the following effects.

(1) First, since the drying lamp according to the first aspect has the base, it can be easily attached to a drying device for an infrared lamp having a normal socket only by replacing the lamp. Further, since the frost layer is applied, the near infrared rays radiated from the bulb are expanded in radiation range by this frost layer portion, and the temperature is made uniform. Further, since the irradiation light is softened, it is possible to reduce the operator's eye strain. Further, since the reflection mirror layer on the inner surface of the shade can provide effective and uniform reflection, good thermal efficiency can be obtained. Further, since the structure is simple, it can be provided at a low cost, and even if about 6 lamps are used in the drying device, it can be said that it is extremely advantageous as compared with the conventional near infrared heater. Further, the present drying lamp consumes less power, has a wide irradiation range, and has a good temperature rising performance, so that an energy saving type, low running cost, and highly efficient lamp can be obtained. In addition, since the filament of the heating element is configured to be supported by the internal lead wire, and the filament is not supported horizontally like the conventional near infrared heater, it is vulnerable to impact like the near infrared heater. Nor.

(2) Next, even in the drying lamp of the above-mentioned claim 2, since it has a base, it can be easily attached to a drying device of an infrared lamp having a normal socket by only replacing the lamp. Further, since the coating layer for radiating far infrared rays is applied, far infrared rays are extremely effectively radiated from the bulb. This results in effective drying, depending on the color of the paint. Further, since the reflection mirror layer on the inner surface of the shade can provide effective and uniform reflection, good thermal efficiency can be obtained. Further, since the structure is simple, it can be provided at a low cost, and even if about 6 lamps are used in the drying device, it can be said that it is extremely advantageous as compared with the conventional near infrared heater. Further, the present drying lamp consumes less power, has a wide irradiation range, and has a good temperature rising performance, so that an energy saving type, low running cost, and highly efficient lamp can be obtained. In particular, because of its structure, the heating of the heating element is immediately transmitted to the coating layer through the glass layer, so that there is no problem that the rising time is long as in the conventional far infrared heater.
